28nm vs other types of lithography? : BitcoinMining

Obelisk's Sia ASICs - Full Details

https://obelisk.tech
Sia is releasing a 28nm, full-custom ASIC. This ASIC will be a complete package, similar to an antminer. You will receive a mining box that includes chips, power supplies, etc. Minimal setup will be required to get the miner working.
The miner is in early development already. We have begun the process of chip design, hardware design, and supply chain management. We have had conversations with previous ASIC manufacturers, and we have been warned about delays, unexpected costs, and myriads of pitfalls that throw off estimations. For this reason, we have set a conservative shipping date of June 2018. If the miners are ready sooner, they will be shipped sooner. If all goes well (and it rarely does, especially for first time manufacturers), we could see the miners shipping before March 2018.
Following the presale, we will be posting a development roadmap on our website that includes all the major steps of development. We will be crossing off steps in the roadmap as we complete them, which will allow the community to follow our progress, have visibility into delays, and will be able to see the places where we are ahead of or behind schedule.
The estimated hashrate is 100 GH/s. We will not know the exact hashrate until later in the development process, however we have confidence that 100 GH/s is a low bar to hit. We may end up shipping miners with a much higher hashrate, and will continue updating the estimated hashrate as we get more accurate estimates for how the chips will perform. The estimated power draw is 500w, though it may be significantly less.
The price of the unit is going to be $2499. Chip manufacturing is expensive, supply chains are expensive, and there are a lot of single-time costs that go into making miners. Future batches will likely have lower prices, however they will also ship later.
We will be selling the miners for Bitcoin. We expect the sale volume to be very large (in the tens of millions of dollars), and we feared that the Sia cryptocurrency would not have enough liquidity to handle all of that volume, resulting in the price rising quickly as people scramble to buy Siacoin for the ASIC, and then the price falling quickly as we convert the Siacoin to USD. This is the worst of both worlds - participants buy the siacoin at a premium, and then we sell them at a discount. Bitcoin has much, much deeper liquidity, and we can sell large volume of Bitcoin quickly without moving the price too much.
We will be converting the Bitcoin to USD as fast as possible. If the price fluctuates by more than 5% before we are able to convert, we will need to request more coins to cover the difference, or cancel the order. If the price fluctuates upwards by more than 5% before we convert, we will return the difference.
The sale and shipment of ASICs on the Sia network is going to dramatically increase the hashrate. When considering how much revenue you may get from a unit, please take into account the fact that we are selling enough units to potentially 10x or 100x the difficulty. If another ASIC manufacturer decides to start selling Sia ASICs, the hashrate may go up by more than just the number of units we sell. Please also consider that the block reward is decreasing. Today, the block reward is about 189,000 siacoins per block. By June 2018, our ship date, the block reward is going to be closer to 135,000 siacoins per block, decreasing by 1 siacoin per block (or 4320 siacoins per month).
The presale will be open for 7 days. There is no rush - people who buy on the fourth day will receive the same treatment as people who buy on the first day. The sale will not close early, and while we reserve the right to deny purchases, we have chosen not to put a cap on the number of units sold. We may pre-sell additional batches before the first batch ships. The first batch will have priority when we begin shipping, and if the later batches will be shipping shortly after, those later batches will be sold at a higher price. People who buy in on the first batch will receive both price preference and shipping date preference as a reward for taking on the most risk.
Obelisk is the company that will be producing these chips. Obelisk is a fully owned subsidiary of Nebulous Inc. Nebulous is the company that employs all of the Sia core developers.
Obelisk has plans for growth in the future. None of these plans are finalized as we are primarily focusing on shipping this miner, but potential future products include:
Finally, we plan to introduce decentralized mining pools into the Sia ecosystem before we ship the miners. Hosts will have the option of running their own mining pool, and then miners can detect the hosts by checking the blockchain and the peer network, forming payment channel contracts with them and participating in fully decentralized mining. This should help alleviate the pool centralization that is seen in most PoW cryptocurrencies.
We are very excited about our new company, and hope that you share in our excitement. Feel free to ask any questions.

11/24/17 Update on Obelisk max hashrate, competing with semi-custom 16nm chips

Some casual conversation from taek posted yesterday. Most of this is out of context and without timestamps because the discord mobile app is 😑.
Context: So from the S7 (28nm) to the first S9 batch (16nm), Bitmain increased hashrate by 2.43x and increased power efficiency by about 2.8x. They are full-custom chips though. I don't know if software routed chips will get that level of improvement.
Also, when S7 was released, an article said: "This chip was built on the 28-nanometer process of Taiwan Semiconductor Manufacturing Company (TSMC); the company felt that it could outperform chips that were built on 14 and 16 nanometer process nodes that didn’t have full custom design techniques."
@SiaBillionaire the non-full custom 16nm chips from Cointerra were about 0.3j / GH. The Butterfly Labs full-custom 28nm chips were also about 0.3j / GH
So basically, as far as Bitcoin was concerned, full-custom 28nm beat out software-routed 16nm between experienced teams. Cointerra I'm pretty sure had 28nm chips as well
So if it's your first rodeo and you are going straight to 16nm having no idea the traditional challenges of mining chips and using software routing, you are not likely to outperform a 28nm full-custom chip from an experienced team
@Wayne we've got simulations saying the SC1 chips can do as much as 3.3 GH/s per watt (as the chip, not as the whole unit), and the DCR1 chips can go as fast as 5.9 GH/s per watt. Then we've got another trick we're using that could push out 5-15% more hashrate.
We've been cautioned though that at these performances the simulations become a lot less reliable.
We push these chips a lot harder than is typical, and the simulations aren't designed around such brutal usage.
Chips are finalized at this point
We can't optimize them any further without pushing back our production timeline significantly

AMD's Growing CPU Advantage Over Intel

https://seekingalpha.com/article/4152240-amds-growing-cpu-advantage-intel?page=1
AMD's Growing CPU Advantage Over Intel Mar. 1.18 | About: Advanced Micro (AMD)
Raymond Caron, Ph.D. Tech, solar, natural resources, energy (315 followers) Summary AMD's past and economic hazards. AMD's Current market conditions. AMD Zen CPU advantage over Intel. AMD is primarily a CPU fabrication company with much experience and a great history in that respect. They hold patents for 64-bit processing, as well as ARM based processing patents, and GPU architecture patents. AMD built a name for itself in the mid-to-late 90’s when they introduced the K-series CPU’s to good reviews followed by the Athlon series in ‘99. AMD was profitable, they bought the companies NexGen, Alchemy Semiconductor, and ATI. Past Economic Hazards If AMD has such a great history, then what happened? Before I go over the technical advantage that AMD has over Intel, it’s worth looking to see how AMD failed in the past, and to see if those hazards still present a risk to AMD. As for investment purposes we’re more interested in AMD’s turning a profit. AMD suffered from intermittent CPU fabrication problems, and was also the victim of sustained anti-competitive behaviour from Intel who interfered with AMD’s attempts to sell its CPU’s to the market through Sony, Hitachi, Toshiba, Fujitsu, NEC, Dell, Gateway, HP, Acer, and Lenovo. Intel was investigated and/or fined by multiple countries including Japan, Korea, USA, and EU. These hazard needs to be examined to see if history will repeat itself. There have been some rather large changes in the market since then.
1) The EU has shown they are not averse to leveling large fines, and Intel is still fighting the guilty verdict from the last EU fine levied against them; they’ve already lost one appeal. It’s conceivable to expect that the EU, and other countries, would prosecute Intel again. This is compounded by the recent security problems with Intel CPU’s and the fact that Intel sold these CPU’s under false advertising as secure when Intel knew they were not. Here are some of the largest fines dished out by the EU
2) The Internet has evolved from Web 1.0 to 2.0. Consumers are increasing their online presence each year. This reduces the clout that Intel can wield over the market as AMD can more easily sell to consumers through smaller Internet based companies.
3) Traditional distributors (HP, Dell, Lenovo, etc.) are struggling. All of these companies have had recent issues with declining revenue due to Internet competition, and ARM competition. These companies are struggling for sales and this reduces the clout that Intel has over them, as Intel is no longer able to ensure their future. It no longer pays to be in the club. These points are summarized in the graph below, from Statista, which shows “ODM Direct” sales and “other sales” increasing their market share from 2009 to Q3 2017. 4) AMD spun off Global Foundries as a separate company. AMD has a fabrication agreement with Global Foundries, but is also free to fabricate at another foundry such as TSMC, where AMD has recently announced they will be printing Vega at 7nm.
5) Global Foundries developed the capability to fabricate at 16nm, 14nm, and 12nm alongside Samsung, and IBM, and bought the process from IBM to fabricate at 7nm. These three companies have been cooperating to develop new fabrication nodes.
6) The computer market has grown much larger since the mid-90’s – 2006 when AMD last had a significant tangible advantage over Intel, as computer sales rose steadily until 2011 before starting a slow decline, see Statista graph below. The decline corresponds directly to the loss of competition in the marketplace between AMD and Intel, when AMD released the Bulldozer CPU in 2011. Tablets also became available starting in 2010 and contributed to the fall in computer sales which started falling in 2012. It’s important to note that computer shipments did not fall in 2017, they remained static, and AMD’s GPU market share rose in Q4 2017 at the expense of Nvidia and Intel.
7) In terms of fabrication, AMD has access to 7nm on Global Foundries as well as through TSMC. It’s unlikely that AMD will experience CPU fabrication problems in the future. This is something of a reversal of fortunes as Intel is now experiencing issues with its 10nm fabrication facilities which are behind schedule by more than 2 years, and maybe longer. It would be costly for Intel to use another foundry to print their CPU’s due to the overhead that their current foundries have on their bottom line. If Intel is unable to get the 10nm process working, they’re going to have difficulty competing with AMD. AMD: Current market conditions In 2011 AMD released its Bulldozer line of CPU’s to poor reviews and was relegated to selling on the discount market where sales margins are low. Since that time AMD’s profits have been largely determined by the performance of its GPU and Semi-Custom business. Analysts have become accustomed to looking at AMD’s revenue from a GPU perspective, which isn’t currently being seen in a positive light due to the relation between AMD GPU’s and cryptocurrency mining.
The market views cryptocurrency as further risk to AMD. When Bitcoin was introduced it was also mined with GPU’s. When the currency switched to ASIC circuits (a basic inexpensive and simple circuit) for increased profitability (ASIC’s are cheaper because they’re simple), the GPU’s purchased for mining were resold on the market and ended up competing with and hurting new AMD GPU sales. There is also perceived risk to AMD from Nvidia which has favorable reviews for its Pascal GPU offerings. While AMD has been selling GPU’s they haven’t increased GPU supply due to cryptocurrency demand, while Nvidia has. This resulted in a very high cost for AMD GPU’s relative to Nvidia’s. There are strategic reasons for AMD’s current position:
1) While the AMD GPU’s are profitable and greatly desired for cryptocurrency mining, AMD’s market access is through 3rd party resellers whom enjoy the revenue from marked-up GPU sales. AMD most likely makes lower margins on GPU sales relative to the Zen CPU sales due to higher fabrication costs associated with the fabrication of larger size dies and the corresponding lower yield. For reference I’ve included the size of AMD’s and Nvidia’s GPU’s as well as AMD’s Ryzen CPU and Intel’s Coffee lake 8th generation CPU. This suggests that if AMD had to pick and choose between products, they’d focus on Zen due higher yield and revenue from sales and an increase in margin.
2) If AMD maintained historical levels of GPU production in the face of cryptocurrency demand, while increasing production for Zen products, they would maximize potential income for highest margin products (EPYC), while reducing future vulnerability to second-hand GPU sales being resold on the market. 3) AMD was burned in the past from second hand GPU’s and want to avoid repeating that experience. AMD stated several times that the cryptocurrency boom was not factored into forward looking statements, meaning they haven’t produced more GPU’s to expect more GPU sales.
In contrast, Nvidia increased its production of GPU’s due to cryptocurrency demand, as AMD did in the past. Since their Pascal GPU has entered its 2nd year on the market and is capable of running video games for years to come (1080p and 4k gaming), Nvidia will be entering a position where they will be competing directly with older GPU’s used for mining, that are as capable as the cards Nvidia is currently selling. Second-hand GPU’s from mining are known to function very well, with only a need to replace the fan. This is because semiconductors work best in a steady state, as opposed to being turned on and off, so it will endure less wear when used 24/7.
The market is also pessimistic regarding AMD’s P/E ratio. The market is accustomed to evaluating stocks using the P/E ratio. This statistical test is not actually accurate in evaluating new companies, or companies going into or coming out of bankruptcy. It is more accurate in evaluating companies that have a consistent business operating trend over time.
“Similarly, a company with very low earnings now may command a very high P/E ratio even though it isn’t necessarily overvalued. The company may have just IPO’d and growth expectations are very high, or expectations remain high since the company dominates the technology in its space.” P/E Ratio: Problems With The P/E I regard the pessimism surrounding AMD stock due to GPU’s and past history as a positive trait, because the threat is minor. While AMD is experiencing competitive problems with its GPU’s in gaming AMD holds an advantage in Blockchain processing which stands to be a larger and more lucrative market. I also believe that AMD’s progress with Zen, particularly with EPYC and the recent Meltdown related security and performance issues with all Intel CPU offerings far outweigh any GPU turbulence. This turns the pessimism surrounding AMD regarding its GPU’s into a stock benefit. 1) A pessimistic group prevents the stock from becoming a bubble. -It provides a counter argument against hype relating to product launches that are not proven by earnings. Which is unfortunately a historical trend for AMD as they have had difficulty selling server CPU’s, and consumer CPU’s in the past due to market interference by Intel. 2) It creates predictable daily, weekly, monthly, quarterly fluctuations in the stock price that can be used, to generate income. 3) Due to recent product launches and market conditions (Zen architecture advantage, 12nm node launching, Meltdown performance flaw affecting all Intel CPU’s, Intel’s problems with 10nm) and the fact that AMD is once again selling a competitive product, AMD is making more money each quarter. Therefore the base price of AMD’s stock will rise with earnings, as we’re seeing. This is also a form of investment security, where perceived losses are returned over time, due to a stock that is in a long-term upward trajectory due to new products reaching a responsive market.
4) AMD remains a cheap stock. While it’s volatile it’s stuck in a long-term upward trend due to market conditions and new product launches. An investor can buy more stock (with a limited budget) to maximize earnings. This is advantage also means that the stock is more easily manipulated, as seen during the Q3 2017 ER.
5) The pessimism is unfounded. The cryptocurrency craze hasn’t died, it increased – fell – and recovered. The second hand market did not see an influx of mining GPU’s as mining remains profitable.
6) Blockchain is an emerging market, that will eclipse the gaming market in size due to the wide breath of applications across various industries. Vega is a highly desired product for Blockchain applications as AMD has retained a processing and performance advantage over Nvidia. There are more and rapidly growing applications for Blockchain every day, all (or most) of which will require GPU’s. For instance Microsoft, The Golem supercomputer, IBM, HP, Oracle, Red Hat, and others. Long-term upwards trend AMD is at the beginning of a long-term upward trend supported by a comprehensive and competitive product portfolio that is still being delivered to the market, AMD referred to this as product ramping. AMD’s most effective products with Zen is EPYC, and the Raven Ridge APU. EPYC entered the market in mid-December and was completely sold out by mid-January, but has since been restocked. Intel remains uncompetitive in that industry as their CPU offerings are retarded by a 40% performance flaw due to Meltdown patches. Server CPU sales command the highest margins for both Intel and AMD.
The AMD Raven Ridge APU was recently released to excellent reviews. The APU is significant due to high GPU prices driven buy cryptocurrency, and the fact that the APU is a CPU/GPU hybrid which has the performance to play games available today at 1080p. The APU also supports the Vulcan API, which can call upon multiple GPU’s to increase performance, so a system can be upgraded with an AMD or Nvidia GPU that supports Vulcan API at a later date for increased performance for those games or workloads that been programmed to support it. Or the APU can be replaced when the prices of GPU’s fall.
AMD also stands to benefit as Intel confirmed that their new 10 nm fabrication node is behind in technical capability relative to the Samsung, TSMC, and Global Foundries 7 nm fabrication process. This brings into questions Intel’s competitiveness in 2019 and beyond. Take-Away • AMD was uncompetitive with respect to CPU’s from 2011 to 2017 • When AMD was competitive, from 1996 to 2011 they did record profit and bought 3 companies including ATI. • AMD CPU business suffered from: • Market manipulation from Intel. • Intel fined by EU, Japan, Korea, and settled with the USA • Foundry productivity and upgrade complications • AMD has changed • Global Foundries spun off as an independent business • Has developed 14nm &12nm, and is implementing 7nm fabrication • Intel late on 10nm, is less competitive than 7nm node • AMD to fabricate products using multiple foundries (TSMC, Global Foundries) • The market has changed • More AMD products are available on the Internet and both the adoption of the Internet and the size of the Internet retail market has exploded, thanks to the success of smartphones and tablets. • Consumer habits have changed, more people shop online each year. Traditional retailers have lost market share. • Computer market is larger (on-average), but has been declining. While Computer shipments declined in Q2 and Q3 2017, AMD sold more CPU’s. • AMD was uncompetitive with respect to CPU’s from 2011 to 2017. • Analysts look to GPU and Semi-Custom sales for revenue. • Cryptocurrency boom intensified, no crash occurred. • AMD did not increase GPU production to meet cryptocurrency demand. • Blockchain represents a new growth potential for AMD GPU’s. • Pessimism acts as security against a stock bubble & corresponding bust. • Creates cyclical volatility in the stock that can be used to generate profit. • P/E ratio is misleading when used to evaluate AMD. • AMD has long-term growth potential. • 2017 AMD releases competitive product portfolio. • Since Zen was released in March 2017 AMD has beat ER expectations. • AMD returns to profitability in 2017. • AMD taking measureable market share from Intel in OEM CPU Desktop and in CPU market. • High margin server product EPYC released in December 2017 before worst ever CPU security bug found in Intel CPU’s that are hit with detrimental 40% performance patch. • Ryzen APU (Raven Ridge) announced in February 2018, to meet gaming GPU shortage created by high GPU demand for cryptocurrency mining. • Blockchain is a long-term growth opportunity for AMD. • Intel is behind the competition for the next CPU fabrication node. AMD’s growing CPU advantage over Intel About AMD’s Zen Zen is a technical breakthrough in CPU architecture because it’s a modular design and because it is a small CPU while providing similar or better performance than the Intel competition.
Since Zen was released in March 2017, we’ve seen AMD go from 18% CPU market share in the OEM consumer desktops to essentially 50% market share, this was also supported by comments from Lisa Su during the Q3 2017 ER call, by MindFactory.de, and by Amazon sales of CPU’s. We also saw AMD increase its market share of total desktop CPU’s. We also started seeing market share flux between AMD and Intel as new CPU’s are released. Zen is a technical breakthrough supported by a few general guidelines relating to electronics. This provides AMD with an across the board CPU market advantage over Intel for every CPU market addressed.
1) The larger the CPU the lower the yield. - Zen architecture that makes up Ryzen, Threadripper, and EPYC is smaller (44 mm2 compared to 151 mm2 for Coffee Lake). A larger CPU means fewer CPU’s made during fabrication per wafer. AMD will have roughly 3x the fabrication yield for each Zen printed compared to each Coffee Lake printed, therefore each CPU has a much lower cost of manufacturing.
2) The larger the CPU the harder it is to fabricate without errors. - The chance that a CPU will be perfectly fabricated falls exponentially with increasing surface area. Intel will have fewer high quality CPU’s printed compared to AMD. This means that AMD will make a higher margin on each CPU sold. AMD’s supply of perfect printed Ryzen’s (1800X) are so high that the company had to give them away at a reduced cost in order to meet supply demands for the cheaper Ryzen 5 1600X. If you bought a 1600X in August/September, you probably ended up with an 1800X.
3) Larger CPU’s are harder to fabricate without errors on smaller nodes. -The technical capability to fabricate CPU’s at smaller nodes becomes more difficult due to the higher precision that is required to fabricate at a smaller node, and due to the corresponding increase in errors. “A second reason for the slowdown is that it’s simply getting harder to design, inspect and test chips at advanced nodes. Physical effects such as heat, electrostatic discharge and electromagnetic interference are more pronounced at 7nm than at 28nm. It also takes more power to drive signals through skinny wires, and circuits are more sensitive to test and inspection, as well as to thermal migration across a chip. All of that needs to be accounted for and simulated using multi-physics simulation, emulation and prototyping.“ Is 7nm The Last Major Node? “Simply put, the first generation of 10nm requires small processors to ensure high yields. Intel seems to be putting the smaller die sizes (i.e. anything under 15W for a laptop) into the 10nm Cannon Lake bucket, while the larger 35W+ chips will be on 14++ Coffee Lake, a tried and tested sub-node for larger CPUs. While the desktop sits on 14++ for a bit longer, it gives time for Intel to further develop their 10nm fabrication abilities, leading to their 10+ process for larger chips by working their other large chip segments (FPGA, MIC) first.” There are plenty of steps where errors can be created within a fabricated CPU. This is most likely the culprit behind Intel’s inability to launch its 10nm fabrication process. They’re simply unable to print such a large CPU on such a small node with high enough yields to make the process competitive. Intel thought they were ahead of the competition with respect to printing large CPU’s on a small node, until AMD avoided the issue completely by designing a smaller modular CPU. Intel avoided any mention of its 10nm node during its Q4 2017 ER, which I interpret as bad news for Intel shareholders. If you have nothing good to say, then you don’t say anything. Intel having nothing to say about something that is fundamentally critical to its success as a company can’t be good. Intel is on track however to deliver hybrid CPU’s where some small components are printed on 10nm. It’s recently also come to light that Intel’s 10nm node is less competitive than the Global Foundries, Samsung, and TSMC 7nm nodes, which means that Intel is now firmly behind in CPU fabrication. 4) AMD Zen is a new architecture built from the ground up. Intel’s CPU’s are built on-top of older architecture developed with 30-yr old strategies, some of which we’ve recently discovered are flawed. This resulted in the Meltdown flaw, the Spectre flaws, and also includes the ME, and AMT bugs in Intel CPU’s. While AMD is still affected by Spectre, AMD has only ever acknowledged that they’re completely susceptible to Spectre 1, as AMD considers Spectre 2 to be difficult to exploit on an AMD Zen CPU. “It is much more difficult on all AMD CPUs, because BTB entries are not aliased - the attacker must know (and be able to execute arbitrary code at) the exact address of the targeted branch instruction.” Technical Analysis of Spectre & Meltdown * Amd Further reading Spectre and Meltdown: Linux creator Linus Torvalds criticises Intel's 'garbage' patches | ZDNet FYI: Processor bugs are everywhere - just ask Intel and AMD Meltdown and Spectre: Good news for AMD users, (more) bad news for Intel Cybersecurity agency: The only sure defense against huge chip flaw is a new chip Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign Take-Away • AMD Zen enjoys a CPU fabrication yield advantage over Intel • AMD Zen enjoys higher yield of high quality CPU’s • Intel’s CPU’s are affected with 40% performance drop due to Meltdown flaw that affect server CPU sales.
AMD stock drivers 1) EPYC • -A critically acclaimed CPU that is sold at a discount compared to Intel. • -Is not affected by 40% software slow-downs due to Meltdown. 2) Raven Ridge desktop APU • - Targets unfed GPU market which has been stifled due to cryptocurrency demand - Customers can upgrade to a new CPU or add a GPU at a later date without changing the motherboard. • - AM4 motherboard supported until 2020. 3) Vega GPU sales to Intel for 8th generation CPU’s with integrated graphics. • - AMD gains access to the complete desktop and mobile market through Intel.
4) Mobile Ryzen APU sales • -Providing gaming capability in a compact power envelope.
5) Ryzen and Threadripper sales • -Fabricated on 12nm in April. • -May eliminate Intel’s last remaining CPU advantage in IPC single core processing. • -AM4 motherboard supported until 2020. • -7nm Ryzen on track for early 2019. 6) Others: Vega, Polaris, Semi-custom, etc. • -I consider any positive developments here to be gravy. Conclusion While in the past Intel interfered with AMD's ability to bring it's products to market, the market has changed. The internet has grown significantly and is now a large market that dominates when in computer sales. It's questionable if Intel still has the influence to affect this new market, and doing so would most certainly result in fines and further bad press.
AMD's foundry problems were turned into an advantage over Intel.
AMD's more recent past was heavily influenced by the failure of the Bulldozer line of CPU's that dragged on AMD's bottom line from 2011 to 2017.
AMD's Zen line of CPU's is a breakthrough that exploits an alternative, superior strategy, in chip design which results in a smaller CPU. A smaller CPU enjoys compounded yield and quality advantages over Intel's CPU architecture. Intel's lead in CPU performance will at the very least be challenged and will more likely come to an end in 2018, until they release a redesigned CPU.
I previously targeted AMD to be worth $20 by the end of Q4 2017 ER. This was based on the speed that Intel was able to get products to market, in comparison AMD is much slower. I believe the stock should be there, but the GPU related story was prominent due to cryptocurrency craze. Financial analysts need more time to catch on to what’s happening with AMD, they need an ER that is driven by CPU sales. I believe that the Q1 2018 is the ER to do that. AMD had EPYC stock in stores when the Meltdown and Spectre flaws hit the news. These CPU’s were sold out by mid-January and are large margin sales.
There are many variables at play within the market, however barring any disruptions I’d expect that AMD will be worth $20 at some point in 2018 due these market drivers. If AMD sold enough EPYC CPU’s due to Intel’s ongoing CPU security problems, then it may occur following the ER in Q1 2018. However, if anything is customary with AMD, it’s that these things always take longer than expected.

Updated FAQs for newcomers

TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party.
Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this?
Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?"
Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here.
Now, why are these changes so large?
A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010.
In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon.
In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips.
In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race.
ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty.
The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months.
Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase.
And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case.
The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
You can check out the manufacturers and their products below along with a calculator here.
If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice.
Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee.
However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
I actually do not use any of the pools recommended to the left because I think they lack features.
My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap.
Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me.
BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised.
All of them pay out transaction fees.

Question on Ethereum mining performance over an array of GPUs

Recently, my friends have begun entering the crypto-currency mining scene. I've dabbled in the past but found that it wasn't for me. Being a fourth year engineering student, however, I am extremely curious about a discrepency I've seen. As far as I can tell the best GPU currently for mining is the R9 390X at 31MH/s. What confuses me is the fact that the 390X, with a single precision compute score of 5.91 TFLOP/s out performs the R9 Fury X (With a single percision compute score of 8.9 TFLOP/s) by almost 10MH/s. I've read that the memory bandwidth available to the GPU factors in, but the Fury X has vastly more bandwidth thatn the 390X. Both chips are also built on the same 28nm process, so lithography doesn't seem to be a factor either. I considered that clock speed might be the reason, but both cards run at the same 1000MHz factory speed. The only other thing I could think of off the top of my head would be the architecture itself. This seems like the most logical answer (seeing as the AMD cards were king over the faster 700 series cards during the Bitcoin mining craze in 2013/2014) but I'm still not entirely clear on the details. These questions have been burning me ever since Bitcoin mining was popularized and I've been dying to know for years. Any help would be greatly appreciated

[ActiveMining / Virtual Mining Corp] Basic facts/summary etc

*On this thread you will find details from the most important Official ACtM news releases, statements and published facts for easy reference. *
Active Mining Corporation (ACtM) is the parent company of Virtual Mining Corp (VMC) and is made up of a team of dedicated Bitcoin mining professionals with over 30 years of combined experience.
The current company structure is as follows:
Active Mining Corporation Management Team:
Kenneth E. Slaughter, CEO/CTO
Virtual Mining Corporation Management Team:
Kenneth E. Slaughter, CEO/CTO Gerald L. Slaughter, COO/CFO Micah Slaughter, VP Manufacturing Operations Darin Carolus, VP Marketing
VMC also has 2 in-house Engineers in San Jose and a Project Manager working very closely with eASIC. ACtM company offices are in Springfield MO - VMC website http://virtualminingcorp.com/index.html
eASIC 28nm ASIC
Since IPO, ACtM/VMC has been perusing a 28nm ASIC chip with eASIC. http://www.easic.com/ In September ACtM and eASIC released a joint statement:
Santa Clara, CA and Springfield, MO – September 4, 2013 – eASIC Corporation, a leading provider of NEW ASIC devices and Virtual Mining Corporation (VMC) today announced that VMC will use eASICs 28nm Nextreme-3 devices to create a series of scalable Bitcoin mining machines capable of generating up to 24.756 TH/s.
The above chip roll-out was delayed by ACtM in September due to concerns over ROI with BTC value at only 140 USD and competitors chips at 4-500GH/s. The ACtM chip was therefore returned to the design stage and the result is a more refined and more efficient full custom 28nm device which eASIC are presently in the process of producing. Chip specs will be known shortly.
This chip will be available for: bulk sales, the ACtM mining farm, and will be sold in premium high-power machines for retail and industrial customers. This chip is expected in Q3 2014.
UMC 55nm ASIC
On the 21st January 2014 ActM surprised investors when they published this press release:
Springfield, MO and Santa Jose, CA – January 21, 2014 – Active Mining Corporation (Belize) (AMC) a bitcoin Mining and Hardware Manufacture, and People's ASIC a stealth Silicon Valley startup founded by two veteran engineers is proud to announce today the tape-out of their 55 nm UMC Bitcoin Mining ASIC. Simultaneously, AMC has acquired the Intellectual Property for the 55nm UMC Bitcoin Mining ASIC. Delivery of chips is expected in Q2/2014. Also, AMC will use the same design team and code which successfully taped out the 55 nm on AMC's eASIC's 28 nm.
This new full custom 55nm project (wholly owned by ACtM) is at a more advanced stage than the eASIC custom 28nm ASIC and has been taped out by UMC. http://www.umc.com/english/process/c.asp This chip will be utilised in scalable bitcoin mining machines capable of generating upto 10.488TH/s.
The published specs of the UMC fabbed chip include: 11mm x 11m package, 1.9 GH/s, 2.5 Watts per chip which is 1.315789474W/GH (before Intellihash is applied)
This chip will be available for: bulk sales, the ACtM mining farm, and will be sold in budget medium-power machines for retail and industrial customers. This chip is expected in Q2 2014.
*Intellihash (TM) * Intellishash (TM) is a unique in-house process designed by ACtM and its engineering team which extends or boosts the usefull hashing life of Bitcoin mining ASIC's. For commercial reasons the full details of this technology are confidential. The process can be applied to ACtM chips and will boost chip lifetime-performance as hash-difficulty rises. The percentage of increased life-time efficiency over a standard ASIC chip is not public knowledge, but the boost is expected to be significant over non-Intellishash capable chips (ie competitors chips).
ACtM mining farm
With their own mining farm ACtM expect to utilise first their 55nm based rigs which generate 10.488 TH/s and shortly after their 28nm based rigs which generate 24.576 TH/s. Electricity costs for ACtM are stated to be around 0.017 $/kWh.
Shares
Due to increased shareholder requests to implement a trading solution ASAP ACtM shares will be listed on Hong-Kong based Crytpo-Trade https://crypto-trade.com/ in the next few days. 28/1/2014.
All shares on Bitfunder were requested to be tendered to the 'AMC-TENDER' holding account before the closure of BF so that Ken could batch-process them onto a new exchange when one was ready. Any holder who carried out the tender on BF should receive an email notification soon which will lead them to log-in to an auto-created account on CryptoTrade. At this point no account needs to be manually opened.
The most recent information on this move is: 'The transfer of shares from AMC-TENDER to Crypto-Trade will be via an automated site. To verify your shares, you will need an email address that you want to register as a account on Crypto-Trade (fine if you already have an account using that email, shares will just be added to that account), the number of shares transferred to AMC-TENDER, and your AMC-TENDER transfer date and time of transfer (from your Bitfunder transfer logs, or from the screenshot you made of the transfer).'
For the many shareholders who did not carry out the BF tender (or who do not have the date and time of your tender), you will likely be requested to confirm your identity by signing from your wallet address which you registered on the Bitfunder site before you can access your CryptoTrade account. Due to the manual processing of your shares (not part of the tender batch-processing) you may gain access to your shares sometime after those who did fulfill the tender request.
Shareholder guarantee
There are a total of 10,000,000 (10 Million) publicly held shares in ACtM that represent interests in all VMC, and ACtM profits. The shareholder guarantee states that these 10M shares will receive all dividends until a total of 0.0025BTC has been paid per share. Currently less than 2% of this total has been paid out. After the 0.0025BTC has been paid to each publicly held share the CEO's holding of 15 Million shares will also begin to receive dividends so that all profits are then shared out equally between the final total of 25,000,000 shares.
Ukyo Shares
Through his Bitfunder securities exchange and WeExchange processing site Ukyo misplaced, lost or miss-invested over 6,000BTC from the community. ACtM had company funds in both Bitfunder (38BTC approx) and WeEx (70BTC approx) which represented assets raised from the IPO, funds for the purposes of paying dividends, and funds being used to transfer ACtM shares to CryptoStocks via a free transfer option for share holders. (This scheme was in it's very early days and so only a few thousand shares were exchanged to CS before Bitfunder was closed). These monies appear to have been lost and after legal notice was served on Ukyo for the return of these funds no refund was made. ACtM has therefore adopted the rights of lien under Corporation Law to seize Ukyo's ACtM share holdings. Ukyo held approx 232,000 shares in ACtM. These shares are being sold on Crypto Trade solely for the purposes of reimbursing ACtM lost funds and legal fees and costs relating to this case. Once these funds have been reimbursed the remaining shares/raised BTC will be returned to either Ukyo or a rightful third party so that the community can get back some of their lost monies. At the current listed price it is expected that only 5% of the seized shares need to be sold to reimburse ACtM leaving 95% for other parties. However should that listed price (0.01BTC) not be reached, more numbers of shares will need to be sold at a lower price.
Pre-order Refunds
With BTC savings retained from the IPO, and BTC having appreciated almost 10fold, ACtM has ample liquid assets to refund 100% of all pre-orders plus continue with full production of the 55nm and 28nm projects. Of the few pre-order customers who have requested a refund all have been repaid in full in a timely manner. Pre-orders paid for in FIAT are currently held in FIAT by the company to safeguard this company liability from a fall in BTC prices.

76 mh/s ASIC scrypt miner now available on TransHash.com

This extremely powerful miner with 48-A2 28nm ASIC chips achieves 76 Mh/s (86 Mh/s in Turbo mode), while only drawing about 400-480 watts of power. It will exponentially increase the power of your mining rig, while also enabling you to contribute to securing the network of any scrypt-based cryptocurrency you choose to mine, a task that is going to require substantial computing power going forward.
This is the first miner TransHash is offering (through a wholesale arrangement with an authorized distributor). We hope you will take a look at this miner and offer your feedback on this product and/or the TransHash website. TransHash accepts payment in bitcoin, litecoin, and dogecoin.
